Custom Features

You can add the following features to your LINE MINI App to further enhance the user experience. The features you can use depend on whether the LINE MINI App is an unverified MINI App or a verified MINI App.

Service Messages

Service messages can be used if you want to send users the confirmation of their restaurant or accommodation reservations.

Service messages is a feature whereby LINE MINI App notifies the user of information the user should know regarding the user's request.

Service messages sent from LINE MINI Apps are displayed in chat rooms determined for each region that provides the LINE MINI App, regardless of the type of LINE MINI App.

Japan	Thailand	Taiwan
LINEミニアプリ お知らせ	LINE MINI App Notice	LINE MINI App 通知

To send a service message, use the service message API. For details, see Sending service messages.

Custom Path

Custom Path is a unique string that is set in the LIFF URL of the published channel. The Custom Path feature allows you to set your own string in the LIFF URL, as follows:

For example, by setting a unique name as a Custom Path, users will be able to identify which brand or shop's LINE MINI App from the URL. For more information on Custom Path, see Configuring Custom Path.

Skip the channel consent process

When a user first accesses a LINE MINI App with the openid scope enabled, the channel consent screen is displayed where they need to consent to their user ID being used within the LINE MINI App.

To simplify this consent process, turn on the "Channel consent simplification" feature for your LINE MINI App on the LINE Developers Console. This will allow users to skip the channel consent screen when accessing another LINE MINI App and start using the service immediately, simply by consenting to the simplification the first time. As a result, users will be able to access LINE MINI Apps more easily.

For more information, see Skipping the channel consent process.

Redirect non-LINE users to a web browser

In the LINE Developers Console, if you enable Redirect non-LINE users to a web browser in the Web app settings tab of the LINE MINI App channel, non-LINE users outside of Japan, Thailand and Taiwan can use the LINE MINI App service via a web browser.

When a non-LINE user opens the LINE MINI App in a web browser, the page shown in the figure below will be displayed. Tap Open in browser on the page and the LIFF endpoint URL will open in their web browser.

By enabling this feature, for example, foreign visitors to Japan who don't use LINE can now use the services of LINE MINI Apps via a web browser without having to install the LINE app.

The display in a web browser is enabled only if the language setting of the user's web browser isn't Japanese, Thai or Traditional Chinese. However, if the LINE app is installed on the user's device, the LINE app may be launched and the user may be redirected to the LINE MINI App.

What to check before enabling the setting

Before enabling the Redirect non-LINE users to a web browser, make sure that the services of your LINE MINI App is available when the LIFF endpoint URL is accessed with a web browser. The LIFF API properties and methods that can be used by web browsers are as follows:

• liff.id
• liff.ready
• liff.init()
• liff.getOS()
• liff.getAppLanguage()
• liff.getLanguage() (deprecated)
• liff.getVersion()
• liff.getLineVersion()
• liff.isInClient()
• liff.isLoggedIn()
• liff.login()
• liff.logout()
• liff.permanentLink.createUrlBy()
• liff.use()

Add a shortcut to your LINE MINI App to the home screen of the user's device

The user can add a shortcut to your LINE MINI App to the home screen of the user's device. This allows the user to access your LINE MINI App directly from the home screen of the user's device.

Using this feature for services that users frequently use, such as membership cards and mobile ordering, can improve the user experience.

For more information, see Add a shortcut to your LINE MINI App to the home screen of the user's device.

Inducing users to add your Official Account as a friend

With LINE MINI App, you can induce users to add your Official Account as a friend from the Channel consent screen or the Verification screen, using the add friend option.

For more information, see Add the LINE Official Account as a friend when you first open the LINE MINI App (add friend option).

Using Payment Systems

Methods of payment other than LINE Pay, such as credit cards, can be integrated into your LINE MINI App. For more information, see Using payment systems.

Custom action button

The built-in action button is provided to enable users to easily share LINE MINI App among friends, but there is also the option of implementing a custom action button.

Common Profile Quick-fill

Quick-fill is a feature that automatically fills in the necessary profile information when you tap Auto-fill in LINE MINI Apps. The information from the Common Profile set up in the Account Center can be easily used in LINE MINI Apps. For more information, see Overview of Common Profile Quick-fill.

By implementing Quick-fill in LINE MINI Apps, users can automatically fill in required information such as addresses and phone numbers with a single tap of a button. This eliminates the need for manual input, making it more convenient for users when making reservations at stores or placing orders on online stores.
